The sunflower (Helianthus annuus) is a flowering annual dicot.
As a dicot, its petals are in lots of 4 or 5. There are two types
of petals on a sunflower.
First there is the small disc florets in the center that form
the seeds. These are very simple flowers with a single circlet of
unassuming petals.
The outer petal-bearing or ray florets are sterile and they
contain the color petals. Numbers differ between varieties, but
they will be in multiples of either 4 or 5.
